SPBCI EIfiA'iI ONfonning part of Letters Patent No. 363,548,.dated May24, 1987'.

Application filed March 1 6, 1887. Serlal No. 2313167, (No model.)

To an whom. it 'ma'y ooztcerm.

Be it known that I, HENRYW. Sonwncnn'm 'DIEK, of the city of Baltimoreand State of Maryland, have --inve'nted ments in Awnings, of which thefollowing" is a specification.

v y invention has reference-more particularly to that class ofstore-awnings in which the awning-sheet is attached at its upper edge Ato a winding-roll and carried at its lower edge by,a.bar on the outerend of arms jointed to the building to swing vertically; 1

The aims of the invention are mainly to provide means for-automaticallylocking the awn ing when extended, so that it may not be lifted' by thewind, and to admit of the awning being extended a greater or less,distance, as the circumstances require.

In the accompanying drawings,- Figures 1, 2, and 3 are sectionalelevations of my a'wning applied to a building, showing the differentpositions which it assumes. Fig. 4 is a crosssection on the line 1 1,Fig. 2. Fig. 5- is a cross section of the device in modified form. Fig.6is a longitudinal section on the line 3 3 of Fig. 4. Fig. 7 is ascctionon the line 5 5 of Fig. 6. Fig. 8 is a horizontal section on the line 66 of Figs. 9 and,12. Fig. 9 is a vertical section on the line 44 ofFigs. 8 and 12. Figs. 10 and 11 are-side elevations showing the awning-frame inmojdified forms; Fig. 12is'a sectional elevation showing thewinding devices in their preferred form.

Referring to Figsfi 1, 2, 3,. 4;, 6, 7, and 12, A represents ahorizontal windi'ng roll, fixed in any suitable support at' the front ofthe building and combined with means of any suitable character to effectits rotation. 1

B B'repre'sent the awningsheet, attached at its upper edgeto-the-winding-roll and at its g I a, 031'- ried at the outer ends ofarms 0, which arms are inner ends to the building'or other fixed supportat b, so that-- they may swing vertically. When the sheet is wound loweror outer edge toahorizontal bar,

be shortened to. admit ofthe this telescopic or extended :jected orextended position, 3' show it in its inner or retracted position.

upright For the purpose of holding the arm down, solthat. the awning maynot be lifted by the action of th'e'wind thereunder, I combine with thearm 0 a brace, D, having one end pivoted to the wall or other support ath, below the.

pivot of the arm (3, and the opposite end con! nected to the arm Ginanymanner which will admit ofits sliding thereon. U

[commonly pivot the arm or brace D to a collar, E, which encircles andis arranged to slide freely on the body-0f arm 0, and in this collar Imount, as shown'in Fig. 6, a springactuated bolt, g, having shoulders g,which enter notches g in the arm 0, so as to lock the brace to thearniand thus hold the awning .secure'ly in its extendedposition. Ialsomount in the sleeve a. leye'r, n, engaging at onei 'end in the'bo'lt andconnected at the opposite end to a cord or wire, 0, which is extendedthrough the brace D or otherwise to'a point near the where it may beconveniently grasped by the operator for th'epurpose of unlockingtheholt, in order that the awning may be folded-upward.

c When the awning is to extend but a few feet from the building," thearm G is made in one rigid piece from end to end, as shown in Fig.

10;,but when'it is ing of great width arm 0 of two parts reqiiiredto'have the awn I prefer to construct the arranged to slide one inrelati'on to .theoth'e'ryso that when in use the'a'rm andthat whenfolded it may parts closing into more compact form. In Figs. 1, 2, 3",4, and 6 arm consists of the tubular portion d, hinged tothe building,and of the outer portion orrod, 6, arranged toslide therein.

may be extended,

whileFigs; 2 and In order .thattheparts e may be automatically projectedas the awning is extended,- I commonly provide the tubular portion dwith.

Fig. 1 shows'thfe portion'einits proa longitudinal slot and extend thelocking s bolt 9 upward through. this slot into engage nie'nt withfthesliding members, as shown in Fig. 6. When, therefore, the" arm Oswingsdownward, the bolt-carried-ohtward by the sliding end of the brace Dacts to force thero'd e outward. When the parts reach their'outer mostposition,

the bolt automatically locks double purpose of locking the part in itsextended position and of locking the part 0 against a rising movement.When it-is required to extend the awni 1g 2. moderate distance beyondthe building, the-bolt y will be unlocked from the rod e before theawning is extended, and, as a consequence, the arm e will remain in itsinner or retracted position, as shown in Fig. 2.

If desired, the brace D maybe pivoted rigidly to an ear on the underside of the rod,

e, as shown in Fig. 5; but in such case the awning will always beextended to'its full width when brought to an operative position.

The advantage of connecting the brace Dto the part e in a detachablemanner lies in the fact that it enables the awning to be extended agreater or less distance at the'willof the attendant. V

Instead ofconstructingthe arm 0 in the telescopic manner before referredto, it may be made of two parts or bars laid side by side and connectedby .clasps or slides f, as shown in Fig. 11. r

The winding-roll may-be operated, asin -Fig. 1, ,by a sprocket-wheel, G,mounted thereonand connected by a chain, H, to a wheel, I, mounted in asupporting-box on the front of the building,and provided with 'anoperating-crank, K. When the. front is of such form as to forbid thedirect extension of the chain to the operating-wheel, the constructionshown in Fig. 12 "may be adopted. In this figure the chain is extendedfrom the pulley G directly through the wall of the building to aninternal pulley, M, the shaft of which, mounted in fixed'bearings,carries a second pulley,

i is extended downward inside the building to the operating-pulley I,which is; in all respects identical with that before referred to.-

. In'order to prevent the accidental or mischievous release of theawning, I mount in the box J a sliding bolt, L, adapted to engage the.chain at one end and provided with a projection, 12, or its equivalent,by which it may be moved. v

It is to be understood that the essence of my invention resides inconnecting the arm 0 to the brace D by asliding connection and a lookingdevice, within the range of mechanical skill without departing from myinvention, the details of the slide and locking device being of minorimportance. 7

combination with the brace Having thus described my invention, what Iclaim isv 1. In an awning-frame, the extensible arm 0, hinged to swingupward'and downward, in D, pivoted to a fixed support and to the slidingmember of the arm 0, substantially as described,whereby;
